DISPENSING CONTAINER.

Application filed June 29, 1926. Serial No. 119,458.

This invention relates to improvements in dispensing containers, and the objects of the invention are to provide a simple and efl'ective form of container for dispensing various materials such as paste, plastics, creams, etc in which the dispensing mechanism will be of the simplest possible character and yet operate to positively dispense .convenient quantities of the material for use as may be required.

Further objects of the invention are to provide a container which may be manufactured in large quantities at low cost and be adaptable for use in various proprietary articles which are sold in containers used by the cover or other. member on the container to actuate the follower to dispense the material. Other features of the invention will appear from the following specification, all constructed and arranged as shown in detail in the accompanying specification and drawings.

In the drawings:

Figure 1 is a sectional elevation of one embodiment of the invention;

Figure 2 is a sectional elevation of an alternative form of the invention;

Figure 3 is a sectional elevation of another alternative form of the invention;

Figure 4 is a section through the follower member;

Figure 5 is a section showing an alternative form of container.

In the drawings, like characters of reference indicate corresponding parts in all figures.

Referring to the drawings, A indicates a suitable form of container of any convenient shape. The container may be made from a variety of kinds of materials selected with reference to the material to be contained therein. It may, for instance, be made of thin sheet metal, celluloid, glass, cardboard, paper, vulcanite, etc. The container in the embodiment illustrated is of cylindrical form enclosed at one end with a cap B having a flange 10 fitting over the cylindrical side 11 of the container. The container or the cap is provided with an orifice through which the material may be extruded.

In the embodiment shown in Figure 1, a dispensing nozzle 12 is provided about the orifice 13. 0 indicates a follower or pressure member mounted after the manner of a piston in the container C and conveniently formed of resilient material which will enable a tight joint to be made with the inner walls of the container and will also form an operative connection between the propelling member D and the follower member C. I have found that cork is a very suitable material for use in the follower 'member. I have found further in using such material that it is desirable to provide sealing means between the member and the walls of the container, and I conveniently effect this by a layer or coating of Wax 14 on the surface of the follower member, a portion of which extends down into the joint between the follower and the inner walls of the container.

The propelling member D is conveniently helical in form, and I provide a very simple connection between the propelling member and the follower (I by merely forcing the propelling memberv through the follower after the manner of a corkscrew, whereby the propelling member will extend through a helical passage in the propelling member. I find it in such a case desirable to lock the propelling member and\the follower membertogether, also to re-enforce'the follower member by a transverse pin 15 which extends between two coils of the spiral. The

propelling member D is preferably in the form of a spring, the spring characteristics performing the additional function which will be hereafter described. One end of the propelling member D is fixedly connected to the underside of the cover B, the latter being rotatable, connection being preferably made immediately adjacent to the orifice 13. The opposite end of the propelling member D may extend adjacent to or against the bottom 16 of the container, which bottom may be provided with a small orifice 17 designed to admit or to prevent the formation of a vacuum,

When the container is filled with material the follower member is preferably adjacent to the bot om there f, The ma rial is filled in the container after which, when the cap or member B is turned, the propelling member D will also be turned and this, extending spirally through the follower C, will draw the follower towards the cover and so extrude the material through the aperture 13. It will be observed that the spring in the member D will serve to hold the cap in posi tion on the container A, and it may also be observed that the spring may be so designed, if desired, that a certain amount of extrusion will take place after turning of the cap or cover. That is to say, during the movement of the cover B the spring will both be unwound and turned through the member C. Upon completion of the moyementot the cap B the spring will rewind, causing continued movement ot the follower C. Whether or not this additional following movement is desirable would depend upon the character and consistency of the material within the container, but the spring arrangement of the follower member enables the result to be .obtai-ned when desired.

The helical spring form of the propelling ueinber D also enables the same to be used as a ,closure or valve for the m terial to be extruded. This may be accomplished by forming a portion oi the spring more closely wound than the remainder, whereby, during portional movement, such closely wound portion will open to permit the extrusion .ot. material therethrough.

In the alternative form of the invention shown in Figure 2, I have shown a closely wound portion 18 on the spring propelling member D. It may be so designed that before movement the portion D will be completelyclosed in such a way that the material may not pass from the outside to the inside of the helin and thus to the opening 18. In such an event it will be desirable to close off the remainder ofthe helix from the material in the container, which maybe done ,by ,prorid ng filli g m mbe 9I 2e 11 ng W th the 111 mb 1 rem he ot m to th Poi where the closely wound portion 18 of the helix begins. 1n this event a cylindrical aperture 20 will be provided through the folowe m b th en er turns o t e hel engaging a suitable spiral groove 21 in the a' ll of he enemi s 2 In perat ng t m ef t tw ntiet h f rs Per en .ef t turning movement of the cap 13 will cause the open .e the clo ly w fl e rert en C n need m vemen w l rea i m ve e of the ie l ew m mb .6 whi h wil .feree th ma e ia in h e ei e be ween t coils of the portion 18 and out through the 'ifie l }FigureB shows a modification of the form shown in Figure 2, the cut-off in this case being formed by a valve plate 22 immediately below theor-ifice 1'3 .and .restingontop of the central portion 23 of the spiral spring D The top-0t this spring is provided with a few extra wider turns 24 which are connected to the underside of the cap B at a point beyond the opening 13. In this form of the invention the initial movement of the cap will cause tightening of the centre portion 23 of the spring D thus drawing th valv pl t 22 aivay'f m th pening 1 and permitting the material to be extruded. Continued movement will draw up the follower-C towards the cap and cause continued extrusion of the material.

alternative form of container A has corrugated walls, and this event the follower member itself may be left in cylindrical shaped corrugations, being filled in by m ns of we; sealing mate i'ial, hi tee rial willspread to fill in all crevices ,or openings between the tollower and the wall of the container. 7

As many changes could be made the b v u en an ma y app y widely difierent embodiments of my invention, within the scope ,of the claims, constructed without departing from the spirit or scope thereof, it ,is intended that all matter contained in the accompanying specification and drawings shall be interpreted as illust f ltive and not in a limiting sense.

What I claim as my invention is:

1. In combination, a container having an orifice, a follower therein, and a spring member operatively connected to the follower adapted, when turned, to move the follower axially of the spring, said spring having a closely wound portion through which the material is forced when opened.

2. In combination, a container having an orifice, a followertherein, and a spring sothat material may only pass through the closely wound portion.

In witness whereof I have hereunto set my hand.
